Specification of Letters Patent.

Patented J une 2, 1914.

Application tiled April 1'?, 1911. Serial No. 621,689.

T0 all whom it may concern: l

Be it known that l, Ci-rnisr GLSEN, a citizen of the United States,residing at lPort Richmond, in the county ot Richmond and State of NewYork, have invented eertam new and useful lmprovements in Hose-Couplers; and l do hereby declare the tollowingI to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved coupler,especially adapted for use as a hose coupler, and, to this end, itconsists et the novel devices and combinations of devices hereinafterdescribed and defined in the claim.

The invention is illustrated in the accompai'iying drawings, whereinlike characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view ot the improved coupler,partly in side elevation and partly in longitudinal section, with someparts broken away; Fig. 2 is a view in side elevation of one of theinner sleeves ot one ot the coupling heads; Fig. 3 is an inner end viewot one et the outer sleeves ot one of the coupling heads; and Fig. 4- isa transverse section taken on the irregular line :at 034 of Fig. 1, withsome parts broken away.

The numeral 1 indicates the inner ends of a pair of hose sections,which, as shown, are dctachably connected by means ot my im provedcoupler. This coupler is made up of a pair of separable andtelescopically connected coupling heads 2 and 3, each of which comprisesan inner sleeve and an outer sleeve. rlhe outer and inner sleeves which,ege to make up the coupling head 2 are in dicated by the numerals l and5, respectively. The. outer and inner sleeves which go to make up thecouplinghead 3 are indicated by the numerals 6 and 7, respectively. T iesleeves of each couplinghead are connected at their adjacentintermediate portions by means ci screw threads 8 and which connectionspermit longitudinal adustment ot one of said sleeves with respect to theother. rlhcse sleeves are also circumferentially spaced apart, forwardof their threaded engagement 8, to term annular seats 9 and into whichseats the ends ci the hose sect-ions 1 are adapted to be inserted.Opposing hose clamping surfaces are formed on the ends of the sleeves ofthe clamping heads 2 and 3, at the entrance to the seats Se), for thepurpose ot securing the hose sections l to the coupling heads 2 and 3and for tormiint;I a water-tight joint there-between. The hose clampingsurfaces on the inner sleeves and 7 are indicated by the num fals 1()and are 'formed by lieveling the outer 'accs of said sleeve outwardlyand inwardly. The hose clamping,1 surfaces on the outer sleeves 4t andt3 are indicated by the numerals 11 and are formed by curving the outerends ot the sleeve outwardly and inwardly in position to overlie thecoperating surfaces 10.

Each of the inner sleeves 5 and 7 is provided with a wrench scat 12, towhich seats a. wrench, not shown, may be applied tor the purpose otrotatingl the inner sleeves with respect to the outer sleeves. As isevident, by reverse rotations oi the inner sleeves with respect to thecuter sleeves, the hose clamping' surfaces 1G and 11 may be moved towardor from each other, at will, and a varying pressure may be applied tothe interposed ends of the hose sections 1.

l The sleeve 7, at its inner end, is internally reduced to form anannular shoulder 13, on which is seated a pliable packing la. The endso1' the sleeves 1 and 5, inward ot their threaded engagement at 8, areconcentrieally spaced apart to attord a seat 15 which is adapted totelescopieally receive the reduced end of the sleeve 7. Diametrieallyopposite bosses 1G are termed on the outer surface and, at the inner endportion ot the sleeve 11. These bosses 1G are each provided with aninternal seat 17 which is open on the inner side et the sleeve 1 and inwhich seat is pivotally mounted a springpressed lock dog 1S. lhe .loclrdogs 1S normally project within the sleeve il: and coperate with a lockgroove 19 formed in the sleeve 'l' to hold the two coupling heads 2 and3 interloclrcd. For action on each et the lock dogs 18, the lock groove19 is provided with reversely acting cam surfaces 20 and 21. Byreversely rotating' the coupling` heads 2 and 8 with respect to eachother, and in a given direction, the cani surfaces 2O are forced ontothe free ends et the lock dogs 19 and thereby draw the coupling heads 2and 3 onto the pliable packing 1st to term water-tight joint between thecoupling` heads r2 and 3. Then, by rotatingthe coupling heads indirections reverse to that just described, the loclr dogs 18 will bebrought into contact with the cam surfaces 2l and will thereby be cammedout or" the lock groove 19 and into position to permit the endwiseseparation of the Coupling heads 2 and 3. To adjustably hold the bcoupling heads 2 and 3, when Connected7 in set positions with respect toeach other, a spring-pressed sliding pawl 22 is mounted for endwisesliding movement in a seat formed in the inner edge of the sleeve 4. Theoperative end of the pawl 22 normally projects through the said seat andin a position to engage a plurality of ratchet teeth 23 formed in theinner edge of the sleeve 6. The sliding pawl 2Q is provided with asuitable operating finger pin 24e which works through a slot in thesleeve 4.

What l claim is: A hose coupler made up of a pair of connected Couplingheads7 each comprising inner and outer sleeves connected by screwthreads and having coperating hose clamping surfaces which are madeadjustable by the rotation/of one of said sleeves with respect to theother, the inner end portion of the two. sleeves of one of said headsbeing spaced apart and adapted to telescopioally receive the innel` endportion of the inner sleeve of the other of said heads, a pliablepacking interposed between the said two inner sleeves, means forpositively drawing said two inner sleeves onto said pliable packingunder a varying pressure, and means for locking the coupling headsagainst accidental separation.

In testimony whereof afiix my signature in presence of two Witnesses.
